NECTIGUT.

CONNECTICUT, A CORPORATION or 001v- TVIQ-I-IOLE SEVV-ON BUTTON.

Application filed November To all whom it may concern:

Be it known that I, FRANKLIN R. WVHITE, a citizen of the United States of America, residing atlVaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Two-l lole Sew-On Buttons of which the following a specification.

My invention relates to new and useful in'iproven'ients in two hole buttons of the sew-on type, and has for an object to so. construct a button that it may be placed in an auton'iatic button sewing machine and guided in its movement to the needle or needles for the purpose of attachment.

The present application is a companion one of four others filed'by me of even date herewith bearing Serial Numbers 69,318, 69,319, 69,321, and 69,822.

Oneof the objects of the present invention is to provide a button wherein the hub has rounded ends and parallel sides while the holes for the thread are arranged in certain relation to said parallel sides, as these parallel sides are adapted to be engaged in a track, trough or chute, so that the buttons will be properly fed beneath the needle or needles. Still another object of the invention is to provide a button which can be guided andcontrolled in its movementto its needle or needles and be prevented from swervmg so the holes will register with the needles when the button reaches its final position beneath the said needle.

As is well known to those skilled in the art of button attaching machines, heretofore it has been necessary to use some very complicated form of mechanism for correctly. centering the button below the needles. With the present invention, however, the construction of the button is such that the buttons cooperate with a much more simple form of guide mechanism and are carefully and correctly guided and controlled to their position beneath the needle.

With the above and other objects in view, the invention consists in certain new and novel arrangements as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred and a slightly modified form of the invention,

Fig. 1 is a top plan View, the dotted lines re, 1925. Serial No. 69,320;

showing the outline of the lower surface from the undersurface of Fig. 5- is a sectional view taken on line- 55' of Fig, 4,. and v I Fig. 6 is a view from the bottom. of the button.

Referring now more in detail to thejpreferred form, I have showna button formed of wood, metal, bone or other suitable material; comprising a body portion 1 which is slightly depressed at its center 2, has the outstanding, rim 3, and the. hub 4: on its un dersurface. Tlhis hu-b- 4, in the early formation of the'button maybecircular in outline, but is then cut away at its sides so that these two sides 5' extend parallel to each other, and in reality form a projection that is adapted to fit within a slot or guideway (not shown)- of a chute in anau tomatic button sewing machine. The ends 6 of the hub are arcuate as may be clearly seen in Figs. 1 and 3, both of these arcs being struck from a common center, or in otherwords, the center of the lower surface of the hub.

The hub is further provided with two holes or openings 7 through which the needles will pass and these holes or openings are so located that if a line be drawn across the hub from end to end, and through the center point onthe surface on the hub, it Wlll coincide with the centers about which the two holes are constructed.

With the buttons formed in this manner, they may be placed in a buttonattaching machine (not shown) and the parallel sides or walls formed in the hub will properly guide and control the button during its movement to the needle or needles.

Referring now to Fig. 4, I have shown a similar button comprising a body portion 8 having the depressed center 9, the rim 10 and the depending hub 11. Likewise the hub is cut to form the two parallel side walls 12 and two holes 13 are provided, but in this instance the holes are arranged in a diiferent position. The purpose of arranging these in a different position is that the needles in the machine may be arranged in a horizontal manner with respect to the hub of the button, rather than int lengthwise direction, and therefore, in this instance, I have shown the two holes 13 located adjacent the respective side walls 12 diametrically opposite each' other, so that, if a line is drawn through their center, it

will pass through the central-- point 14 of.

the hub. I

The contour of the two ends of the hub is formed by striking two arcs with the point 14 as a center.

From the foregoing it will be seenthat 'I have constructed a button which is exceedingly cheap to manufacture,and wherein the side walls of the hub are constructed so that they may cooperate with a track or chute (not shown) of an automatic button sewing machine, to guide and control the button in its movement to the needle.

By having the ends ofthehub rounded,

the button may pass into the chute if it is facing in one of two directions. The shape of the body and the shapeof the rim are not important, the gist of the invention being the rounded ends of the hub,the parallel sides and the respective positions of the holes.

Other slight changes might be made without in any Way departing from the spirit and scope of the invention.

Having thus described the same, what I claim as new and desire to secure by Letters Patent is':' v

1. A two-hole sew-on button comprising a body portion, a hub, said hub having parallelside walls and rounded endsQthe said hub provided with two holes each located equidistant from the'central point on the. hub surface,-and the side walls adapted to guide the movement of the button in a button sewing machine.

' 2. A two-hole sew-on button comprising a body portion, a depending hub, said hub being rounded at its opposite ends and having side walls parallel with each other merging with the rounded ends, the said hub provided with two holes each of which is equidistant from the said two parallel side Walls, and the side walls adapted to guide the button when fed in a button attaching machine.

3. A two-hole sew-on button comprising .a body portion, a depending hub, the said the said body portion being depressed at its centerand having a downwardly extending hub, said hub provided with two openings therein and the said hub being rounded at its ends and having parallel side walls merg-.

ing with said ends, and the said holes diametrically opposite each other and equidistant'from the said side walls, the said side walls'adapted to control the movement when the button is used in a button attaching machine.

In testimonywhereof I affix my signature.
